If you’re 100% ready then talk to her about it. We stress no relationship talks because they usually don’t end well but if you’re ready to walk then it’s ok. It’s actually the mature alpha thing to do. You are lovely communicating that you would love to work things out but if she’s not interested then you will go find someone who wants to be with you.
Now having said that if she says she’s not interested and you don’t follow through you will remain in limbo until she’s ready to D you or she changes her mind. She will have zero worries of losing you.
